This is where the term "leverage" gets its common definition, often applied well outside the realm of physics: using a relatively smaller amount of power (often in the form of money or influence) to gain a disproportionately greater advantage on the outcome. Types of Levers When using a le...
aA culture, then, is by definition at least, a set of cultural objects. Anthropologist Leslie White asked: "What sort of objects are they? Are they physical objects? Mental objects? Both? Metaphors? Symbols? Reifications?" In Science of Culture (1949), he concluded that they are objects ...
Wheelchair handrim propulsion comprises a push phase in which the user applies force to the handrims to generate propulsion torque around the wheel axle, and a recovery phase when the user releases the hands from the handrims to initiate the next push phase. However, the mechanical efficiency o...
A detailed definition of b can be found in the cited references [1,2,3]. The inertance ratio is defined as μb = b/m1. The lever mass is ignored in the following discussion μ32 = 0 given its minor influence in a practical application. For a fair comparison, the effective mass of...
success. This paper focuses specifically on higher education students’ academic and social involvement, notably through their engagement in extracurricular activities and decision-making processes, which are perceived as critical mechanisms in their persistence in higher education. The study used a ...
Definition 𝐵𝐴𝑖BiA is the coordinate representation of vertices in a fixed reference frame, 𝑄𝐴QA is the position vector of the center point Q of the moving platform in the fixed reference coordinate system O-XYZ, 𝑅𝐴𝐵RBA is the coordinate conversion moment of the moving plat...
